The category "DLC" as we use the term locally is one that meets the following criteria:

(1) 040 code ‡a DLC ‡c DLC -- i.e., a record both catalogued and entered in
machine-readable form by the Library of Congress -- provided that the Encoding level is:

(a) Full level -- Encoding level blank or 1 (number "one")

or

(b) Core level -- Encoding level 4

or

(2) 040 code ‡a other than DLC, but ‡c or ‡d code DLC and 050 field with both indicators "00"
(often, although not always, including 042 field with "lccopycat" code).

The following categories of records are not treated as DLC records:

(1) Records with 040 ‡a DLC but a code other than DLC in 040 ‡c. This category is member-input LC,
records that were originally catalogued by the Library of Congress but input in machine-readable form by a
different, OCLC-member library. For guidelines on cataloguing this category, see
"Member-Input LC Copy Editing Guidelines (Books Format)."

Matching record: The online record must match the book that is being cataloged.
If there is any discrepancy in the title (245), edition (250), imprint (260), physical description (300), or series (4xx) field,
check with Bruce or your trainer before using the record. (Further guidelines are in the document
"Editions and Printings, or, Which Record to Use and How to Edit It.")

Previous CIP: Watch out for and correct data based on previous CIP information that do not accurately reflect the published item.

Multivolume sets: If a record that you are cataloging indicates a multivolume set, give the item(s) to
Bruce if you have not yet been trained to catalog multivolume sets.

Serials: Watch out for possible serials or indexes to serial publications. Give
possible serials or serial indexes to Bruce to check whether they are wanted by the Serials Dept.

Looseleaf materials: If you are cataloguing looseleaf materials, consult with your trainer
before proceeding. They may present special problems in the 260, 300, and/or 500 fields.

Photocopies: If the piece-in-hand is a photocopy of any kind, including University Microfilms International
reproductions, consult with your trainer before proceeding if you have not already been given
instructions for cataloging photocopies.

Accompanying materials: Watch for accompanying computer disks, CD-ROMs, DVDs, sound recordings, maps, microforms,
and other supplementary materials not bound in with the main piece. They may present special problems in the 260, 300,
and/or 5xx fields. Information in the matching record must match the piece and vice versa. Consult
with your trainer before proceeding if you have not already been trained in cataloging accompanying materials.

"Bound-with"s: If your piece consists of two or more separate bibliographic entities that have been bound
together subsequent to publication, each title should be catalogued in a separate bib record. Consult with
your trainer before proceeding.

Defective copies: Watch for possible defects in the book copy, including but not limited to missing pages, pages or sections bound upside down,
pages that protrude from the binding, blurred printing, or defective bindings. Give defective copies to Bruce.

Accept or change information in the DLC record as instructed in these guidelines. Accept
any other fields that may appear in the record but that are not specifically mentioned.

Proofing the record:

Typos and misspellings, including missing and erroneous diacritics, should
be corrected. If a Romance-language title or name is present all in upper case on the title page, determine
whether diacritics need to be added when represented online in 100, 245, 246 field, etc., if you
are familiar with the language. However, do not spend much time checking dictionaries.

E.g. T.p.: LES ELEVES DE MARS Record 245: ‡a Les eleves de Mars

Edit to: Les élèves de Mars [if you know French or see the title written
with accents elsewhere in the piece]

E.g. T.p.: ANDRES ZUNIGA Record 245: ... ‡c Andres Zuniga

Edit to: Andrés Zúñiga [if you know Spanish or see the name written
with accents elsewhere in the piece]

Punctuation and capitalization throughout the record are acceptable as they appear, unless they are misleading.

Tags, indicators, and subfield delimiters must be properly set in all checked and required fields.

Watch:

The filing indicator in the following fields must be correctly set so
that these titles will index properly in Voyager:

1st indicator: 130, 630, 730, 740

2nd indicator: 240, 245, 440, 830

E.g. 245 14 The man in the moon

Watch:

246 field: Delete any initial article in a 246 field, so that the title will index properly in Voyager.

‡t in 4xx, 6xx, 7xx, and 8xx fields: Delete any initial article in the ‡t subfield, so that these titles will index properly in Voyager.

Terminology:

Accept: The information in the online record may be accepted without checking it against the
book. Any fields that are not specifically mentioned in these procedures can also be accepted. (MARC coding errors and actual
DLC typos should be corrected, however.)

Check: The data in the online record should be checked against the book and corrected
accordingly. The term "check" by itself means that missing fields or subfields should not be added.

Check. Delete any initial article. Do not add unless the 245 title proper (‡a subfield) includes an
ampersand (&) in the first five indexed words (i.e., excluding initial article) and a 246 or
740 with the spelled-out form of the ampersand is not already given. When adding the variant title,
provide a 246 field with the indicator "3" and spell out the ampersand in the appropriate language.

Check. At least one place and publisher given in the record must match
one place and publisher in the book. If you are not certain whether you have a match, consult with
Bruce or your trainer before proceeding.

Do not add additional place(s) and publisher(s) in book not given in record. Check distributor data;
do not add.

If date given in record does not match (or if dates do not match),
consult with Bruce or your trainer before proceeding.

Check ‡a and ‡b subfields. However, it is never necessary to verify the number of plates given,
unless there is an obvious discrepancy.

Accompanying material: If ‡e subfield is given in record, make sure that the relevant
accompanying material is present; otherwise, check with Bruce. Consult with Bruce or your trainer for
special instructions if there are accompanying computer disks, CD-ROMs, DVDs, sound recordings, microforms, etc., unless
you have already been trained in cataloging accompanying materials. (See also
note on accompanying material under 5xx fields).

Check if you can verify within the book. Accept other notes unless you know that they are incorrect.

Generally, do not add or change notes, except in the following areas:

Limited edition (500/590): Watch out for books with limited editions
of 300 copies or less or that are autographed copies. These books are candidates for rare or lal,rare
location. Consult with Bruce or your trainer before proceeding.

Check; do not add note unless book is sent to rare or lal,rare. If a specific copy
number is given in an existing note, change the copy number to match the number in the book. If a note needs to be
added, add as a separate 590 field. Also add in the MARC holdings record, in a
852 ‡z public notes subfield.

Accompanying material or supplement (500): Check if item is present;
otherwise, check with Bruce. If data must be added to record, it may be done either in 300 field ‡e subfield or
in 500 field. Consult with Bruce or your trainer if you are unsure how to create necessary note(s).
